i was thinking plant growth but that already has one and it got me to thinking of a new ability. How about Fruit Harvesting (not sure of the name) accelerating the growth/age of vegetation/fruit to the stage of harvesting/eating.

I don't know Pippy was the only person to use it, and with a minor character so she didn't really expand on the limits. There was just a little bit in the profile. The character also has Florakinesis and Terrakinesis though, so I think EC would just be getting info from the earth or the abilities would overlap.
